Filed: 1992-02-26
Abstract: PURPOSE: To increase the magnetic force part of an element while decreasing capacity and limiting leak current, by isolating the element with a field oxide having a wider lower part buried in a semiconductor substrate. CONSTITUTION: A first oxide 14 and a side wall 15 are removed and then a second oxide and a third nitride are deposited sequentially on the entire surface. The third nitride is then etched by RIE, for example, to form a side wall 17a and oxygen or nitrogen ions are implanted into a silicon substrate 11 at low energy. Subsequently, a field oxide 18 is deposited at the part on the silicon substrate 11 implanted with oxygen ions by heat treatment process at 800-950 deg.C and then the side wall 17a, a second oxide 16, a first nitride 13 and a pad oxide 12 are removed, thus forming a buried reverse T-shaped field oxide 18. Finally, a gate 19 and a source-drain region 20 are formed in a region isolated by the buried reverse T-shaped field oxide 18, thus preventing increase of capacity due to p-n junction.

Filed: 1981-05-18
Abstract: PURPOSE:To allow air cooling to be thoroughly useful and to make compact and light in weight by a construction wherein the end base of a heat pipe is made to stick to a laser discharge tube and a radiating fin is provided by fixing it into the front end part of the heat pipe. CONSTITUTION:When a laser discharge tube 10 is laid horizontally, the central part of a heat pipe 11 in the form of a sheet is wound on the tube to form a heat receiving assembly 12 on the one hand, whereas both ends of the heat pipe 11 is made to stick themselves together to form a radiator assembly 13. The reason for this is that radiating fins 14 are planted to supply air for cooling purposes.Even when the laser discharge tube is installed vertically, the heat generated from the laser discharge tube 20 may be effectively radiated through the heat pipe 21 and the tube may be sufficiently cooled. Use of heat pipes 11, 21 made of aluminum or aluminum alloy and extruded into sheets facilitates their assembling.

Filed: 1981-05-18
Abstract: PURPOSE:To simplify the wiring of a battery powdered vehicle by employing a complete 2-wired wiring for an automotive driving motor and a body-earth wiring for loads and forming the body earthing circuit of the loads through a fuse  when a key switch is closed ON. CONSTITUTION:Since a normal-open contact 69b of a relay 69 is opened when a key switch 29 is opened, a negative electrode of a battery 1 is not connected to  a body 33. Since the relay 69 is operated so that the contact 69b is closed when  the switch 29 is then closed, the negative electrode of the battery 1 and the  body 33 are connected through a fuse 79, and the negative sides of respective automotive units 67 are connected to the negative electrode of the battery 1. A  vehicle driving motor M is connected via a lone across the battery 1. Since the  body is thus earthed, the earthing wires for the automotive units of small capacity can be significantly reduced.

Abstract: PURPOSE:To autonomously match a timing skew generated by a delay of a signal in a connecting path between devices by providing a transmission inhibiting signal generating means and a transmission permitting signal generating means on this interface device for controlling the transmission of data to plural devices. CONSTITUTION:To a transfer control part 11, a transmitting signal C10 is applied from a pre-stage part, and in response to a fall of the transmitting signal C10, data is given to a data holding circuit 12 from the pre-stage part. The transfer control part 11 applies a transmission permitting signal AK10 of an 'L' level to the pre-stage part. This transmission permitting signal AK10 of an 'L' level shows a transmission inhibiting state. When a transmission permitting signal AK20 of an 'H' level is applied from a transfer control part 21, the transfer control part 11 applies a transmitting signal C20 of an 'L' level to the data holding circuit 12 and the transfer control part 21 through a buffer 13. This transmission permitting signal AK20 of an 'H' level shows a transmission permitting state. In such a way, a timing skew of a signal in a connecting path between devices can be matched autonomously.

Abstract: PURPOSE:To prevent occurrence of interaction between resistors when a plurality of resistors are connected to the same terminal by forming conductor of the same material as a resistance film and providing a cutout on the conductor resistance film in the vicinity of the leading electrode. CONSTITUTION:A thermal Ta oxide film 2 is formed on a glazed ceramic substrate 1, and Ta nitride film 3 is formed thereon as a resistance material.

The Ta nitride film is partly converted into anodized film 4 on the surface to roughly regulate the resistance value, and the leading electrode B is made of Cr film 8, Ni film 9, Au film 10 and solder bump 11. In this manner, when the resistors 14, 15 are laser trimmed in fine adjustment, since there is the cutout 12 thereon, interaction between the resistors can be eliminated. Since particular conductor is not necessarily provided at the leading electrode, it can be inexpensively formed.
